Through opposite lateral plates(3,3a) of the hopper are penetrated first to fourth slide bars(4,4a,4b,4c) spaced apart from one another by a regular distance. The second and fourth slide bars, respectively located below the first and third slide bars, are alternately arranged therewith. At an inner bottom plane of the tank is installed an inclined screen(6), so that coin-shaped magnets are attached to the screen. At a lower end of the hopper is installed a filtering net(7) having holes(7a), which are adapted to pass a predetermined size of chips.

Abstract: PURPOSE: A ferroelectric memory cell is provided to prevent a data fail by precharging a read bitline in a read operation mode, and to perform a fast operation by accessing the cell data stored in the latch part of a sense amplifier in the read operation mode. CONSTITUTION: A pull-up switch(41) pulls up a supply voltage in enabling a pull-up enable signal. The first latch part latches the supply voltage applied from the pull-up switch, connected as a cross coupled structure between the nodes at both ends of a cell. In enabling a write enable signal, a write control part(32) selectively outputs the data respectively applied through a pair of write bitlines to the nodes at both ends of the cell. A ferroelectric capacitor part(33) generates a voltage difference at both ends of the cell in enabling a cell plate signal to store the data. A pull-down switch(42) pulls down a ground voltage in enabling a pull-down enable signal. The second latch part latches the ground voltage applied from the pull-down switch, connected as a cross coupled structure between the nodes at both ends of the cell. In enabling a read enable signal, a read control part(35) selectively outputs the data stored in the ferroelectric capacitor part to a pair of read bitlines.
